Upgrade Orleans v3 documentation snippets from net6.0 to net10.0

[Copilot]

Nine Orleans 3.x documentation snippet projects were targeting net6.0, which reached end-of-life in November 2024. Updated all to net10.0 per agent instructions.

Changes

• Updated TargetFramework property from net6.0 to net10.0 in 9 .csproj files across:

  • docs/orleans/grains/snippets-v3/ (code-generation, grainservices)
  • docs/orleans/host/configuration-guide/snippets-v3/ (client-config, local-dev, server-config)
  • docs/orleans/host/snippets-v3/ (client)
  • docs/orleans/snippets-v3/ (helloworld)
  • docs/orleans/streaming/snippets-v3/ (streams-quickstart)
  • docs/orleans/tutorials-and-samples/snippets-v3/ (custom-storage)

• Added explicit TargetFramework property to helloworld.csproj (was previously implicit)

All Orleans package references remain at version 3.7.2. Validation confirmed all 37 Orleans snippet projects build successfully.

Consider upgrading projects to either the Standard Term Support (STS) or Long Term Support (LTS) versions.

If any of these projects listed in this issue are intentionally targeting an unsupported version,
you can optionally configure to ignore these results in future automation executions.
Create a (or update the) dotnet-versionsweeper.json file at the root of the repository and
add an ignore entry following the
globbing patterns detailed here.

{
    "ignore": [
        "**/path/to/example.csproj"
    ]
}

Pull request overview

This PR attempts to upgrade Orleans v3 documentation snippet projects from net6.0 (which reached end-of-life in November 2024) to a supported .NET version. However, there is a critical issue: the PR updates all projects to net10.0, which does not exist. The linked issue #51418 specified net8.0 as the target LTS version, but the agent instructions incorrectly specified net10.0.

Changes:

• Updated TargetFramework from net6.0 to net10.0 in 9 .csproj files
• Added explicit TargetFramework property to helloworld.csproj
